WPF Custom Fast Implementation thread wait function Fasttask

In WPF implementation

We often need to achieve this goal: a thread that performs complex tasks, and then the main form waits for animation

I wrapped my simplest things, more convenient to use, we can also be convenient to use

1: Add Commhelper class Fasttask method

Using system;using system.collections.generic;using system.linq;using system.text;using System.Windows;using Loadingindicators.wpf;using system.threading.tasks;namespace plc_data_backup{public class CommHelper {Publi c static void Fasttask (action _actiondoing, action _actionafter=null) {Processcontrol loading = new Pro            Cesscontrol ();                    Task T = new Task (() = {try {_actiondoing (); Application.Current.Dispatcher.BeginInvoke (new Action () = {Loadin                    G.close ();                    }));                if (_actionafter! = null) {_actionafter ();} } catch (Exception ex) {Application.Current.Dispatcher.Invoke (new Action (() = {loading.                        Close (); MessageBox.Show ("failed \ r \ n" + EX.tostring ());//new Popupwindow ().                    Showthis ("Drawing failed");                }));            }            });            T.start (); Loading.            ShowDialog ();        ; }    }}

Fasttask (Action _actiondoing, action _actionafter = null)

_actiondoing is waiting to do things,

_actionafter is the thing to do after waiting to be done, if cross-threading, consider calling across threads

2: Add an animated  DLL

3: Start Testing

private void Button_Click (object sender, RoutedEventArgs e)        {            commhelper.fasttask (new Action () =                {                    Thread.Sleep (1000);//dry complex things                }),                new Action (() =                {                    MessageBox.Show ("Load Complete");                });        }

　　

, easy to use in the future!
